All releases of ReactOS

Release Notes:
This release adds preliminary support for USB mice, keyboard, and storage devices, a rewritten session management subsystem, an alternate ReactOS Memory Management Module which has taken over all memory management responsibilities except for sections, AHCI support with an updated UniATA driver, preliminary support for debugging ReactOS components using windbg, improvements based on results from the AutoHotKey application functionality test suite, and bugfixes based on running Driver Verifier on several bundled drivers.

Release Notes: CMake and MSVC efforts continue and a variety of linking bugs have been resolved due to differing strictness between GCC and MSVC. Service control manager events are now logged in the system log.
Service startup and shutdown has been cleaned up significantly. The pagefile has been limited to 2GB in size due to FAT limitations.

Release Notes: A rewrite of the kdcom kernelmode library, which is now much more compatible with the Microsoft version. This allows for improved built-in support for WinDbg. Support for delay loaded DLLs has been added to the build tools, providing delay loading functionality for shipped libraries. Support for Chinese and Korean fonts has been added. A selection of application compatibility improvements can now been seen, including Opera, Open Office, Firefox 3.5, VLC1.1, and Skype. Synchronization of most of the Wine usermode DLLs and some Win32 subsystem code shared with Wine.

Release Notes: Various NDIS and AFD problems have been solved, which increases compatibility with third party NIC drivers and hardening of the network stack. Preliminary support was added for sound via the new Kernel Streaming service. It's now possible to use the ac97 driver via the new Port Class library to play sound bytes using winamp. The command prompt is more compatible. Many bugfixes were made to the kernel mode portion of the GDI, resulting in a much improved drawing engine across all bit depths.

Release Notes: Various bugfixes and enhancements to kernel core services (e.g. registry, system information routines, sync primitives like guarded mutex, I/O support, and others). An initiative has been started to fix the remaining unstable parts of the kernel: Memory Manager, caching code, and filesystem driver APIs and other dependencies of Mm. Introduction of a new Portable Structured Exception Handling mechanism (PSEH 2.0). Various GDI drawing problems were fixed.

Release Notes: x64 architecture support was improved. A real MSVC compiler support project was started. Kernel improvements and bugfixes were made in quite a few parts: Configuration Manager, IO Manager, KE, Memory Manager, Object Manager, Process Manager. The network stack was improved with leakage fixes and increased functionality. Filesystem driver fixes were made, making them more compatible with the Microsoft NT cache manager. Win32 subsystem improvements and synching of most of the Wine usermode DLLs were done.

Release Notes: The Cm (Config Manager a.k.a. registry support) in
ntoskrnl was completely rewritten. This makes it
much more compatible with NT5.2 (win2k3). A
plug-n-play keyboard and mouse driver was added.
All usermode DLLs were synchronized with the most
recent Wine release. Support for RPC and IDL
(which was quite outdated and buggy) was finally
brought up to date, providing a solution for the
plug-n-play manager problems, ReactOS Services,
and promising future support for complex
applications such as Microsoft Office. Huge
improvements were made to user32, which now uses
the desktop heap, greatly speeding up the UI.

Release Notes: Kernel improvements bringing many areas closer to NT 5.2. Improved hardware support. A stability increase in many core modules, especially win32k. Many changes to base system drivers aimed at increasing compatibility and stability. A rewrite of a number of kernel modules is finished; others have bugfixes to improve stability. A download utility has been added. There are improvements to many of the core user mode applications and control panel applets.

Release Notes: Mainly, the work focused on rewriting certain parts of the ReactOS Core. Freeldr was improved. HAL's key areas have been significantly improved. The Kernel experienced a massive rewrite of incompatible parts. The run-time library (Rtl) has many improvements and bugfixes. Bugs were fixed in kernel mode drivers, and a better USB driver was added. Registry support has been greatly improved by a library (cmlib) shared by the boot loader and the kernel to handle binary registry hives. More fixes in the Win32 subsystem and user mode DLLs. A boot video driver and a splash screen were added.

Release Notes: This release's main feature is the networking
ability. It's the first release where it is
possible to browse the Web or share files via
Samba-TNG. The kernel, drivers, applications,
control panel applets, Win32 subsystem, and boot
loader were changed, improved, and fixed.
